Can you attach the dmesg of a successful boot and an lspci -vxx Thanks Created attachment 149559 [details]
dmesg output
here's one
Created attachment 149560 [details]
portege p2000 lspci
and the other
just trying 2.6.20-1.2967 and got same errors. here's some more details: the following messages are in there somewhere - simplex DMA is claimed by other device, disabling DMA configured for PIO0 EH complete (HSM violation) whilst noting all that i actually left it running longer than before and it got past that bit. the last bits are: ata1.00: configured for PIO0 sd 0:0:0:0: SCSI error: return code = 0x08000002 sda: Current [descriptor[: sense key: Aborted Command Additional sense: Scsi parity error Descriptor urk. it's gone now. the system seems to be running but it's extremely slow. if it ever makes it to a login prompt at a useable speed i'll try to get another dmesg output before i go back to 2.6.20-1.2962.fc7. "Simplex DMA is claimed by other device, disabling DMA" is the root cause of the very slow performance, and I fixed that partly and Petr posted a fix to my fix last night. ata1.00: configured for PIO0 sd 0:0:0:0: SCSI error: return code = 0x08000002 sda: Current [descriptor[: sense key: Aborted Command Additional sense: Scsi parity error Tht bit is most peculiar however okay. so it's possible there's some problem with PIO mode? how about we wait for your fix to turn up in devel and then see if we can reproduce this weird error by manually disabling DMA mode? (by the way, the messages are hand-typed .. it should be "[descriptor]", not "[descriptor[" .. in case you were wondering!) for completeness ... i've tried booting to just a shell but i can't write anything to the disk. (i can remount rw with lots of those errors but actually writing anything to the disk fails with another error) but i can 'dmesg | more' to make a more careful copy of the messages. looks like there's a pattern. you get six copies of a 7 line block which starts with ATA: abnormal status 0x58 on port 0x000101f7 includes the DMA messages and ends with ata1: EH complete and those six blocks are followed by the SCSI error. just updated to 2.6.20-1.2982 and it boots fine. :-) tried booting with "nodma" option. i'm not sure if that's still supposed to have an effect but it didn't make any difference. 'hdparm -d /dev/sda' just returns '/dev/sda:' either way. anyway, i guess the weird messages were just weird and nothing more. i'm happy to try some things out if you do want to investigate that further but otherwise i'm equally happy for you to close this call. many thanks for the responses and fix. |
